Thanks I'll give that a go.. by computer blue screened about an hour later and factorio never crashed on old build so would make sense.

Had multiple crashes after playing the game for ~15 minutes - does not seem to be related to any in game actions. Started when moving to a new PC so possibly a hardware thing. Save, dmp, Mods and Confg attached. edit: Save file too big so it is here: https://drive.google.com/file/d/1b7Fsqrd9-NMvNyH6...
